Pre-Cal help please, I need help with last 2 questions!!?
a. Explain the effect of c on the graph of y = f(x) for the function y = f(x) + c.
shifts the graph up or down so its a vertical shift
b. Explain the effect of c on the graph of y = f(x) for the function y = f(x + c).
Phase shift. It shifts the graph right and left ( horizontal shift )
c. Compare the graphs of y = f(x) and y = -f(x).
is a reflection in the x-axis
d. Compare the graphs of y = f(x) and y = f(-x).
is a reflection in the y-axis
e. Explain the effect of c on the graph of y = f(x) for the function y = cf(x).
f. Explain the effect of c on the graph of y = f(x) for the function y = f(cx).
I need help with E and F please!!
